Sorry if this in the wrong place, but I'm not sure where else to post, and I'm not sure where to look, either.
Basically, I want to solder 2 female USB-A ports to a single micro USB-B plug, so that 2 devices (such as a keyboard and mouse) can be plugged in simultaneously. Is this a straight-forward process or does this require a whole interface to be built?
Reason for this is that I would like to plug those into my android device, but currently I can only plug in 1 device at a time.
Any replies will be appreciated.
